Katarina Stewart is a pre-made Sim from Midnight Hollow. She has a passion for dolls at a young age, and underwent a plastic surgery to become like her beloved doll, which can be noted by her large eyes and small nose. She lives alone at 84 True Terrace, which is shaped like a dollhouse.
Katarina is employed in the Spa Specialist part-time career as a Clothes Folder. If the player wants to fulfill her lifetime wish, he/she will need to have her quit her part-time career. She is romantically interested with the toy collector Jack Limb and acquainted with Joaquin Dorsey and Josie Crane. She has two points in the Cooking skill at the start of the game.
She may be a spoof of a Barbie doll or perhaps she could be a spoof of Victoria Everglot from Corpse Bride. She could even be a reference to strange girl to ParaNorman or to the real-life human barbie, Valeria Lukyanova. It is also possible that she may see Jack Limb as her Ken doll.
